Answer:
A. There are fossils of extinct ancestors of horseshoe crabs and the species is still alive today.
Explanation:
C and D have more to do with how it can be a fossil. It is a living fossil because its ancestors have been found in fossils, yet it continues to live today.
Answer:
The correct answer is option a.
Explanation:
Yes, the light reactions also depend upon the Calvin cycle. Calvin cycle refers to a phenomenon that is used by the plants and algae to convert carbon dioxide from the atmosphere into sugar, the food needed by the autotrophs in order to grow. The plants rely upon the Calvin cycle for food and energy.
In the given case, the rate of oxygen production would get diminish as the rate of ATP and NADP+ generated by the Calvin cycle diminishes. Of all the outcomes of the Calvin cycle, ADP and NADP+ are the only ones that get utilized by light reactions.
The ADP and NADP+ are used up by the light reactions to fuel their reactions. This illustrates that if the rate of ADP and NADP+ generated by the Calvin cycle diminishes the production of oxygen by the light reactions also diminishes.
The right option is the second option, which states "<span>fur color that closely matches the eucalyptus bark color</span>". Change is in the fur color of Koala's to match the bark color of eucalyptus tree is a structural adaptation that fits them for their habitat as tree-dwellers.
In this case, the ribosomes organelles of Satyrinae and Charazinae are expected to be most similar.
<h3>What is evolution?</h3>
Evolution refers to the descendence with modification and therefore differences are lesser in close species.
According to the tree, the statement 'Nymphalidae share a common ancestor with other butterflies' best supports the theory of evolution.
In conclusion, in this case, the ribosomes organelles of Satyrinae and Charazinae are expected to be most similar.
